摘要/描述

Nanoscale zero-valent iron (nZVI) used to remediate contaminated groundwater is limited due its lack of durability and mechanical strength. To address these issues, synthesized kaolin supported nanoscale zerovalent iron (K-nZVI) was used to remove Pb (II) ion from aqueous solution. This study has demonstrated that synthesized K-nZVI was efficient in removing Pb (II) from aqueous solution containing 500mgL−1 of Pb (II), where 90.1% of Pb (II) was removed within 60 min using 5g L−1 of K-nZVI having a nZVI mass fraction of 20% at pH 5-6. Ni (II) and Cd (II), as co-existent ions, were also removed by the synthesized KnZVI. This however had little effect on the removal of Pb (II) from solution. The synthesized K-nZVI could be reused more than 5 times when applied to remove Pb (II) from solution with concentrations of 50mgL−1. Additionally, synthesized K-nZVI was efficient in removing Pb (II) (98.8%) and total Cr (99.8%) from an electroplating wastewater, indicating that the synthesized nZVI is a potential remediation material when used for the treatment of electroplating wastewater containing metal ions.
